嘿伙计们，我的应用程序登录凭据的身份验证有问题。我目前有一个从我的本地主机运行的 Rails Web 服务，它具有一个主登录屏幕，供管理员用户使用密码凭据来显示功能。
问题是我正在创建一个与我的 rails 应用程序一起运行的 RESTful iOS 应用程序，它只接受这些 JSON 请求并绕过它们。
我想要的只是为我创建一种无需使用 auth_token 即可输入管理员和密码的方法？这似乎是唯一的方法，首先在钥匙串中简单地验证管理员用户。我使用框架 AFNetowrking 进行身份验证。SSKeychain 是帐户的包装器，而 SVProgressHUD 是轻量级的 hud
.我还在 i 终端中记录了 JSON 和 XML 请求，但由于无法连接到服务器并出现此错误而失败
error Domain=NSURLErrorDomain Code=-1004 "Could not connect to the server." UserInfo=0x7556d50 {NSErrorFailingURLStringKey=http://localhost:3000.json/, NSErrorFailingURLKey=http://localhost:3000.json/, NSLocalizedDescription=Could not connect to the server., NSUnderlyingError=0xeb805c0 "Could not connect to the server."}
这就是我为 authClient 存储凭据的方式，所有想要做的就是指定用于登录 Web 服务客户端的相同信息。
用户名：admin 和密码：taliesin
但不确定如何做到这一点？
这些就是我对 AuthAPIClient、CredentialsStore 和 LoginViewController 的要求
如果有人知道更简单的方法，请更新，请告诉我，将不胜感激。
